Forget the typically awkward name: this is an all new Windows smartphone experience. Microsoft Windows Phone 7 Series is a complete re-build of Windows Mobile, with a spartan interface replacing the clutter that had become synonymous with the platform. Key features of the new OS are a series of "hubs" dedicated to specific activities, including one for people that integrates contact information with that person's various online social networking accounts; a pictures hub for viewing, sharing, and taking pictures and video; a hub for games that offers complete integration with Xbox LIVE; the new music and video hub that borrows heavily from the Zune HD to offer complete Zune functionality and competent media playback; a new marketplace hub for purchasing and downloading new applications; and an Office hub for all you productivity types.
